/** |
|
30 |
* Convenience class for writing character files. The constructors of this |
|
31 |
* class assume that the default character encoding and the default byte-buffer |
|
32 |
* size are acceptable. To specify these values yourself, construct an |
|
33 |
* OutputStreamWriter on a FileOutputStream. |
|
34 |
* |
|
35 |
* <p>Whether or not a file is available or may be created depends upon the |
|
36 |
* underlying platform. Some platforms, in particular, allow a file to be |
|
37 |
* opened for writing by only one <tt>FileWriter</tt> (or other file-writing |
|
38 |
* object) at a time. In such situations the constructors in this class |
|
39 |
* will fail if the file involved is already open. |
|
40 |
* |
|
41 |
* <p><code>FileWriter</code> is meant for writing streams of characters. |
|
42 |
* For writing streams of raw bytes, consider using a |
|
43 |
* <code>FileOutputStream</code>. |
